July 29 (Bloomberg) -- Ophir Energy Plc, a U.K. explorer in
East and West Africa, rose in London trading after announcing a
natural gas discovery in waters off Tanzania.

Ophir added 2.4 percent to 387.70 pence as of 8:11 a.m. in
London.

Ophir and BG Group Plc’s Mkizi-1 well encountered gas in
three reservoir intervals with net pay of 33 meters (108 feet),
Ophir said in a statement today in London. Estimates for the
recoverable resource were in line with pre-drill estimates of
0.6 trillion cubic feet.

BG last week raised its resource estimate for discoveries
in Tanzania with Ophir to 13 trillion cubic feet of gas. The
Deepsea Metro 1 drillship that made the lastest discovery, which
is located between two others in Block 1, will now move to drill
two appraisal wells.
